A Dot blot (or Slot blot) is a technique in molecular biology used to detect biomolecules. It represents a simplification of the northern blot, Southern blot, or western blot methods. In a dot blot the biomolecules to be detected are not first separated by chromatography. Instead, a mixture containing the molecule to be detected is applied directly on a membrane as a dot. This is then followed by detection by either nucleotide probes (for a northern blot and Southern blot) or antibodies (for a western blot).
